C A R S EAT SPECIFICATION forming part of Letters Patent No. 476,728,dated J une '7, 1892. Application filed December 15,1891. Serial No.415.131. (No model.)

To @ZZ whom, t may concern:

Be it known that we, EDWIN L. BUSHNELL and GEORGE IV. DRYER, citizens ofthe United States of America, residing at Poughkeepsie, in the county ofDutchess and State of New York, have invented certain new and usefulImprovements in Oar-Seats, of which the following is a specification.

Our invention relates to reversible car-scats of that class in which theback is supported upon a striker-arm, and is thereon shifted from sideto side and at the same time reversed and held in the proper position bymeans of a supplemental arm.

Our invention is an improvement in thc construction and combination ofthe supplemental arm, with other parts hereinafter described, whereby itis adapted to the long striker-arm, and whereby, also, the mechanism isbetter litted to car-seats.

Our invention is illustrated in the accompanying drawings, in which-Figure l shows a side elevation of the in ner face of the end frame of aseat with the striker-arm and supplemental arm. Fig. 2 shows a sectionon line :r :n of Fig. l. Fig. 3 is a section on line y y of Fig. l.

In the drawings, A represents the arm of an ordinary end frame of aear-scat, having the ordinary plate l) for attachment to the end ot` theback, to the ear of which plate the free end of the striker-arm ispivoted at c. The striker-arm C is of the class known as longstriker-arms, the lower end of it being pivoted in a fixed support at ornear the plane of the seat, the pivot being indicated at d, this pivotbeing at a point in the central vertical line of the said frame. Uponthe arm O is pivoted a supplemental arm E, the pivot being shown at c.One end of the pivot e Works in a slot, so as to permit slightlongitudinal as well as rotary movement of the supple mental arm on itspivot. The upper end of the supplemental arm is pivoted to the ear ofthe plate b at the point f, within or inside the pivot c, in the normalposition of the back and below the pivot c, when the back is beingturned, where the main arm O is pivoted to the ear, these two pointsbeing substantially in a line at right angles to the general planeinterposed between their lower ends.

of the back. The lower end of the striker arm C has a curved slot j",struck from the pivot CZ as a center, the arm being enlarged to givespace for the slot. In this slot is seated the pivot g of the link G,the pivot g being in the same vertical line as the pivot d of the thearm C and below the pivot d. This pivot-pin g projects from the frameand is a rigid part thereof, the link G moving thereon. The link G ispivoted to the striker-arm C at the point h, being substantially in aline drawn through the pivots c d and a little below the pivot d. Thelink G is recessed on its under face to allow play of the pin 7L duringreversal of the back. The lower end of the supplemental arm E is pivotedto the link at a point i', which is on the line drawn through theeenters of the pivots g h when the arm is in vertical position. Theconstruction is such that the supplemental arm may move freely over theface of the strikerarm, the link G being I/Vhen the striker-arm is movedon its pivot, as in the act of shifting the back from one side to theother of the seat, the slotted portion of the striker-arm below itspivot moves in an opposite direction upon the pivot g of the link. Thefirst effect or the etfect of the first part of this movement (supposingthe striker-arm to be at the limit upon one side) is to move thesupplemental arm longitudinally upon the striker-arm, and at the sametime to give it slight pivotal movement, which increases as the centralor pivotal lines of the two arms approach coincidence with each other.At this point of coincidence the two arms are vertical and the pivotsare all in the same line, so that the back is a horizontal midwayposition. The arms continuing their movement to their opposite limit,the position of the arm and the back is reversed to that which theyoccupied at the beginning of the movement. The position at the end ofthe movement, as described, is of course the same relatively as at thebeginning of the movement, the position only being reversed.

In addition to the construction of the arms above described, we havedevised a block or casting upon which are pivoted these arms,

this being shown at H, This block is pref- IOO erably made of castmetal, and can be east in proper shape in one piece. It is capable ofbeing placed, as shown, between the posts of the end frame, and maybeadded to the seatframes now in use. The block is made with a cut-awayportion having inclined shoulders 7o', against which the supplementalarm E bears at the end of its movement, and within these shoulders areother shoulders k, against which the edges of the main striker-arm Cbears similarly at the end of the movement. The block is also formedwith a cavity below to receive the lower ends of the arms with the linksand to permit them to move. Upon the lower end ot' the striker-arm isthe ordinary pin m for shifting the seat. The link is shown in the formof a disk; but this particular form is not material. The upper part ofthe striker-arm has marginal diverging tlangespn, between which thesupplemental arm moves and against which its edges rest at the limit ofmovement.

The block lfI may be cast with the supporting flanges 0 0 for the seat.

Upon the outer face of the striker-arm is a lock, the bolt of whichbears upon the curved face of the block and engages with holes at theends. The arm being released, the back is moved and turns simultaneouslyon its pivot with the arms, and is locked thereon when the striker-armis locked at the end of the movement. As the arms are all supported onthe block, the whole back-support can be made and itted together andapplied to ordinary car-seats, old or new, and by simply extending thearms a very high back may be used and still be reversed within a spaceof thirty (30) inches.

The illustration shows the arms and blocks at one end only; but it willbe understood that the same are duplicated at the other end of the seat,the lock excepted.

We claim as our inventionl. In combination, striker-arms pivoted on asuitable support, a seat-back pivoted on the striker-arms, asupplemental arm pivoted on one of said striker-arms and to the back,and

a pivoted-link connection interposed between the lower end of thesupplemental arm and the striker-arm, substantially as described.

2. In combination, striker-arms pivoted on a suitable support, aseat-back pivoted on the striker-arms, a supplement-al arm pivoted onone of said striker-arms and to the back, a curved slot in the lower endof said strikerarm, a link turning upon a pivot passing through saidslot, said link being pivoted to the supplemental arm, and a looseconnection between said link and the striker-arm, substantially asdescribed.

3. In combination with the end frames of a car-seat, blocks forming apart thereof, strikerarms pivoted to said blocks, a seat-back, a

supplemental arm carried by one of the striker-arms, both the strikerand supplemental arms being also pivoted to the seatback, a second pivotg in the block, a link turning on said pivot and connected to thesupplemental arm, and a loose connection between the link andstriker-arm,substantially as described.

ln testimony whereof We aflix our signatn res in presence of twowitnesses.
